A method of controlling a buoyancy system for an aircraft includes: determining the roll angle .phi. and the pitching angle .theta. of the aircraft; verifying whether -.phi..sub.R <+.sub.R and whether -.theta..sub.R <.theta.<+.theta..sub.R, where .phi..sub.R and .theta..sub.R are predefined limit angles; if at least one of the angles .phi. and .theta. is no longer in its above-defined respective range, activating an automatic trigger of the buoyancy system; if the angles .phi. and .theta. are in their above-defined respective ranges, determining the altitude A of the aircraft; inhibiting the automatic trigger if A >A.sub.R, where A.sub.R is a predefined limit altitude; and if A.sub.R .gtoreq.A, and if at least partial immersion of the aircraft has been detected, activating the automatic trigger.
